I was wondering if it was abnormal to have dreams and better recall of them after only 10-20 minutes of sleep. I woke up this morning and set my alarm clock to go off in 20 minutes. I slept, had a dream, and remembered it. When I woke up again, I set my clock for another 10 minutes, and I again recalled my dream.

I only ask this because I'm having trouble recalling during the night. Before going to bed, I repeat to myself "I will remember my dream and wake up to record them." Well, I wake about an hour and a half later (REM period), but I can't recall my dream. Atleast I'm getting it half right.
